+FlauBERT
+----------------------------------------------------
+
+The FlauBERT model was proposed in the paper
+`FlauBERT: Unsupervised Language Model Pre-training for French <https://arxiv.org/abs/1912.05372>`__ by Hang Le et al.
+It's a transformer pre-trained using a masked language modeling (MLM) objective (BERT-like).
+
+The abstract from the paper is the following:
+
+*Language models have become a key step to achieve state-of-the art results in many different Natural Language
+Processing (NLP) tasks. Leveraging the huge amount of unlabeled texts nowadays available, they provide an efficient
+way to pre-train continuous word representations that can be fine-tuned for a downstream task, along with their
+contextualization at the sentence level. This has been widely demonstrated for English using contextualized
+representations (Dai and Le, 2015; Peters et al., 2018; Howard and Ruder, 2018; Radford et al., 2018; Devlin et
+al., 2019; Yang et al., 2019b). In this paper, we introduce and share FlauBERT, a model learned on a very large
+and heterogeneous French corpus. Models of different sizes are trained using the new CNRS (French National Centre
+for Scientific Research) Jean Zay supercomputer. We apply our French language models to diverse NLP tasks (text
+classification, paraphrasing, natural language inference, parsing, word sense disambiguation) and show that most
+of the time they outperform other pre-training approaches. Different versions of FlauBERT as well as a unified
+evaluation protocol for the downstream tasks, called FLUE (French Language Understanding Evaluation), are shared
+to the research community for further reproducible experiments in French NLP.*

 ## What is Distil*
 
-Distil* is a class of compressed models that started with DistilBERT. DistilBERT stands for Distillated-BERT. DistilBERT is a small, fast, cheap and light Transformer model based on Bert architecture. It has 40% less parameters than `bert-base-uncased`, runs 60% faster while preserving 97% of BERT's performances as measured on the GLUE language understanding benchmark. DistilBERT is trained using knowledge distillation, a technique to compress a large model called the teacher into a smaller model called the student. By distillating Bert, we obtain a smaller Transformer model that bears a lot of similarities with the original BERT model while being lighter, smaller and faster to run. DistilBERT is thus an interesting option to put large-scaled trained Transformer model into production.

+# Swedish BERT Models
+
+The National Library of Sweden / KBLab releases three pretrained language models based on BERT and ALBERT. The models are trained on aproximately 15-20GB of text (200M sentences, 3000M tokens) from various sources (books, news, government publications, swedish wikipedia and internet forums) aiming to provide a representative BERT model for Swedish text. A more complete description will be published later on.
+
+The following three models are currently available:
+
+- **bert-base-swedish-cased** (*v1*) - A BERT trained with the same hyperparameters as first published by Google.
+- **bert-base-swedish-cased-ner** (*experimental*) - a BERT fine-tuned for NER using SUC 3.0.
+- **albert-base-swedish-cased-alpha** (*alpha*) - A first attempt at an ALBERT for Swedish.
+
+All models are cased and trained with whole word masking.

+
+TensorFlow model weights will be released soon.
+
+## Usage requirements / installation instructions
+
+The examples below require Huggingface Transformers 2.4.1 and Pytorch 1.3.1 or greater. For Transformers<2.4.0 the tokenizer must be instantiated manually and the `do_lower_case` flag parameter set to `False` and `keep_accents` to `True` (for ALBERT).
+
+To create an environment where the examples can be run, run the following in an terminal on your OS of choice.
+
+```
+# git clone https://github.com/Kungbib/swedish-bert-models
+# cd swedish-bert-models
+# python3 -m venv venv
+# source venv/bin/activate
+# pip install --upgrade pip
+# pip install -r requirements.txt
+```
+
+### BERT Base Swedish
+
+A standard BERT base for Swedish trained on a variety of sources. Vocabulary size is ~50k. Using Huggingface Transformers the model can be loaded in Python as follows:
+
+```python
+from transformers import AutoModel,AutoTokenizer
+
+tok = AutoTokenizer.from_pretrained('KB/bert-base-swedish-cased')
+model = AutoModel.from_pretrained('KB/bert-base-swedish-cased')
+```
+
+
+### BERT base fine-tuned for Swedish NER
+
+This model is fine-tuned on the SUC 3.0 dataset. Using the Huggingface pipeline the model can be easily instantiated. For Transformer<2.4.1 it seems the tokenizer must be loaded separately to disable lower-casing of input strings:
+
+```python
+from transformers import pipeline
+
+nlp = pipeline('ner', model='KB/bert-base-swedish-cased-ner', tokenizer='KB/bert-base-swedish-cased-ner')
+
+nlp('Idag släpper KB tre språkmodeller.')
+```
+
+Running the Python code above should produce in something like the result below. Entity types used are `TME` for time, `PRS` for personal names, `LOC` for locations, `EVN` for events and `ORG` for organisations. These labels are subject to change.
+
+```python
+[ { 'word': 'Idag', 'score': 0.9998126029968262, 'entity': 'TME' },
+  { 'word': 'KB',   'score': 0.9814832210540771, 'entity': 'ORG' } ]
+```
+
+The BERT tokenizer often splits words into multiple tokens, with the subparts starting with `##`, for example the string `Engelbert kör Volvo till Herrängens fotbollsklubb` gets tokenized as `Engel ##bert kör Volvo till Herr ##ängens fotbolls ##klubb`. To glue parts back together one can use something like this:
+
+```python
+text = 'Engelbert tar Volvon till Tele2 Arena för att titta på Djurgården IF ' +\
+       'som spelar fotboll i VM klockan två på kvällen.'
+
+l = []
+for token in nlp(text):
+    if token['word'].startswith('##'):
+        l[-1]['word'] += token['word'][2:]
+    else:
+        l += [ token ]
+
+print(l)
+```
+
+Which should result in the following (though less cleanly formated):
+
+```python
+[ { 'word': 'Engelbert',     'score': 0.99..., 'entity': 'PRS'},
+  { 'word': 'Volvon',        'score': 0.99..., 'entity': 'OBJ'},
+  { 'word': 'Tele2',         'score': 0.99..., 'entity': 'LOC'},
+  { 'word': 'Arena',         'score': 0.99..., 'entity': 'LOC'},
+  { 'word': 'Djurgården',    'score': 0.99..., 'entity': 'ORG'},
+  { 'word': 'IF',            'score': 0.99..., 'entity': 'ORG'},
+  { 'word': 'VM',            'score': 0.99..., 'entity': 'EVN'},
+  { 'word': 'klockan',       'score': 0.99..., 'entity': 'TME'},
+  { 'word': 'två',           'score': 0.99..., 'entity': 'TME'},
+  { 'word': 'på',            'score': 0.99..., 'entity': 'TME'},
+  { 'word': 'kvällen',       'score': 0.54..., 'entity': 'TME'} ]
+```
+
+### ALBERT base
+
+The easisest way to do this is, again, using Huggingface Transformers:
+
+```python
+from transformers import AutoModel,AutoTokenizer
+
+tok = AutoTokenizer.from_pretrained('KB/albert-base-swedish-cased-alpha'),
+model = AutoModel.from_pretrained('KB/albert-base-swedish-cased-alpha')
+```

+### ALBERT base
+
+The easisest way to do this is, again, using Huggingface Transformers:
+
+```python
+from transformers import AutoModel,AutoTokenizer
+
+tok = AutoTokenizer.from_pretrained('KB/albert-base-swedish-cased-alpha'),
+model = AutoModel.from_pretrained('KB/albert-base-swedish-cased-alpha')
+```

+
+## Dataset
+UmBERTo-Commoncrawl-Cased utilizes the Italian subcorpus of [OSCAR](https://traces1.inria.fr/oscar/) as training set of the language model. We used deduplicated version of the Italian corpus that consists in 70 GB of plain text data, 210M sentences with 11B words where the sentences have been filtered and shuffled at line level in order to be used for NLP research.

+# German BERT
+
+## Overview
+**Language model:** bert-base-cased   
+**Language:** German  
+**Training data:** Wiki, OpenLegalData, News (~ 12GB)  
+**Eval data:** Conll03 (NER), GermEval14 (NER), GermEval18 (Classification), GNAD (Classification)  
+**Infrastructure**: 1x TPU v2  
+**Published**: Jun 14th, 2019
+ 
+## Details
+- We trained using Google's Tensorflow code on a single cloud TPU v2 with standard settings.
+- We trained 810k steps with a batch size of 1024 for sequence length 128 and 30k steps with sequence length 512. Training took about 9 days.
+- As training data we used the latest German Wikipedia dump (6GB of raw txt files), the OpenLegalData dump (2.4 GB) and news articles (3.6 GB).
+- We cleaned the data dumps with tailored scripts and segmented sentences with spacy v2.1. To create tensorflow records we used the recommended sentencepiece library for creating the word piece vocabulary and tensorflow scripts to convert the text to data usable by BERT.
+
+See https://deepset.ai/german-bert for more details
+
+## Hyperparameters
+
+```
+batch_size = 1024
+n_steps = 810_000
+max_seq_len = 128 (and 512 later)
+learning_rate = 1e-4
+lr_schedule = LinearWarmup
+num_warmup_steps = 10_000
+```
+
+## Performance
+
+During training we monitored the loss and evaluated different model checkpoints on the following German datasets:
+
+- germEval18Fine: Macro f1 score for multiclass sentiment classification
+- germEval18coarse: Macro f1 score for binary sentiment classification
+- germEval14: Seq f1 score for NER (file names deuutf.\*)
+- CONLL03: Seq f1 score for NER
+- 10kGNAD: Accuracy for document classification
+
+Even without thorough hyperparameter tuning, we observed quite stable learning especially for our German model. Multiple restarts with different seeds produced quite similar results.
+  
+![performancetable](https://thumb.tildacdn.com/tild3162-6462-4566-b663-376630376138/-/format/webp/Screenshot_from_2020.png)  
+
+We further evaluated different points during the 9 days of pre-training and were astonished how fast the model converges to the maximally reachable performance. We ran all 5 downstream tasks on 7 different model checkpoints - taken at 0 up to 840k training steps (x-axis in figure below). Most checkpoints are taken from early training where we expected most performance changes. Surprisingly, even a randomly initialized BERT can be trained only on labeled downstream datasets and reach good performance (blue line, GermEval 2018 Coarse task, 795 kB trainset size).

+# German BERT
+
+## Stats
+
+In addition to the recently released [German BERT](https://deepset.ai/german-bert)
+model by [deepset](https://deepset.ai/) we provide another German-language model.
+
+The source data for the model consists of a recent Wikipedia dump, EU Bookshop corpus,
+Open Subtitles, CommonCrawl, ParaCrawl and News Crawl. This results in a dataset with
+a size of 16GB and 2,350,234,427 tokens.
+
+For sentence splitting, we use [spacy](https://spacy.io/). Our preprocessing steps
+(sentence piece model for vocab generation) follow those used for training
+[SciBERT](https://github.com/allenai/scibert). The model is trained with an initial
+sequence length of 512 subwords and was performed for 1.5M steps.
+
+This release includes both cased and uncased models.
+
+## Model weights
+
+Currently only PyTorch-[Transformers](https://github.com/huggingface/transformers)
+compatible weights are available. If you need access to TensorFlow checkpoints,
+please raise an issue!

+Library open sources Italian BERT models 🎉
+
+# Italian BERT
+
+The source data for the Italian BERT model consists of a recent Wikipedia dump and
+various texts from the [OPUS corpora](http://opus.nlpl.eu/) collection. The final
+training corpus has a size of 13GB and 2,050,057,573 tokens.
+
+For sentence splitting, we use NLTK (faster compared to spacy).
+Our cased and uncased models are training with an initial sequence length of 512
+subwords for ~2-3M steps.
+
+For the XXL Italian models, we use the same training data from OPUS and extend
+it with data from the Italian part of the [OSCAR corpus](https://traces1.inria.fr/oscar/).
+Thus, the final training corpus has a size of 81GB and 13,138,379,147 tokens.

+# Multilingual + Dutch SQuAD2.0
+
+This model is the multilingual model provided by the Google research team with a fine-tuned dutch Q&A downstream task.
+
+## Details of the language model(bert-base-multilingual-cased)
+
+Language model ([**bert-base-multilingual-cased**](https://github.com/google-research/bert/blob/master/multilingual.md)):
+12-layer, 768-hidden, 12-heads, 110M parameters.
+Trained on cased text in the top 104 languages with the largest Wikipedias.
+
+## Details of the downstream task - Dataset
+Using the `mtranslate` Python module, [**SQuAD2.0**](https://rajpurkar.github.io/SQuAD-explorer/) was machine-translated. In order to find the start tokens the direct translations of the answers were searched in the corresponding paragraphs. Since the answer could not always be found in the text, due to the different translations depending on the context (missing context in the pure answer), a loss of question-answer examples occurred. This is a potential problem where errors can occur in the data set (but in the end it was a quick and dirty solution that worked well enough for my task).
+
+| Dataset                | # Q&A |
+| ---------------------- | ----- |
+| SQuAD2.0 Train         | 130 K |

+| SQuAD2.0 Dev           | 12  K |
+| Dutch SQuAD2.0 Dev     | 10  K |
+
+## Model training
+
+The model was trained on a Tesla V100 GPU with the following command:
+
+```python
+export SQUAD_DIR=path/to/nl_squad
+
+python run_squad.py \
+  --model_type bert \

+# BETO (Spanish BERT) + Spanish SQuAD2.0
+
+This model is provided by [BETO team](https://github.com/dccuchile/beto) and fine-tuned on [SQuAD-es-v2.0](https://github.com/ccasimiro88/TranslateAlignRetrieve) for **Q&A** downstream task.
+
+## Details of the language model('dccuchile/bert-base-spanish-wwm-cased')
+
+Language model ([**'dccuchile/bert-base-spanish-wwm-cased'**](https://github.com/dccuchile/beto/blob/master/README.md)):
+
+BETO is a [BERT model](https://github.com/google-research/bert) trained on a [big Spanish corpus](https://github.com/josecannete/spanish-corpora). BETO is of size similar to a BERT-Base and was trained with the Whole Word Masking technique. Below you find Tensorflow and Pytorch checkpoints for the uncased and cased versions, as well as some results for Spanish benchmarks comparing BETO with [Multilingual BERT](https://github.com/google-research/bert/blob/master/multilingual.md) as well as other (not BERT-based) models.

+
+Distillation makes the model **smaller, faster, cheaper and lighter** than [bert-base-spanish-wwm-cased-finetuned-spa-squad2-es](https://github.com/huggingface/transformers/blob/master/model_cards/mrm8488/bert-base-spanish-wwm-cased-finetuned-spa-squad2-es/README.md)
+
+This model was fine-tuned on the same dataset but using **distillation** during the process as mentioned above (and one more train epoch).
+
+The **teacher model** for the distillation was `bert-base-multilingual-cased`. It is the same teacher used for `distilbert-base-multilingual-cased` AKA [**DistilmBERT**](https://github.com/huggingface/transformers/tree/master/examples/distillation) (on average is twice as fast as **mBERT-base**).

+
+A Greek version of BERT pre-trained language model.
+
+<img src="https://github.com/nlpaueb/GreekBERT/raw/master/greek-bert-logo.png" width="600"/> 
+
+
+## Pre-training corpora
+
+The pre-training corpora of `bert-base-greek-uncased-v1` include:
+
+* The Greek part of [Wikipedia](https://el.wikipedia.org/wiki/Βικιπαίδεια:Αντίγραφα_της_βάσης_δεδομένων),
+* The Greek part of [European Parliament Proceedings Parallel Corpus](https://www.statmt.org/europarl/), and
+* The Greek part of [OSCAR](https://traces1.inria.fr/oscar/), a cleansed version of [Common Crawl](https://commoncrawl.org).
+
+Future release will also include:
+
+* The entire corpus of Greek legislation, as published by the [National Publication Office](http://www.et.gr),  
+* The entire corpus of EU legislation (Greek translation), as published in [Eur-Lex](https://eur-lex.europa.eu/homepage.html?locale=en).
+
+## Pre-training details
+
+* We trained BERT using the official code provided in Google BERT's github repository (https://github.com/google-research/bert). We then used [Hugging Face](https://huggingface.co)'s [Transformers](https://github.com/huggingface/transformers) conversion script to convert the TF checkpoint and vocabulary in the desirable format in order to be able to load the model in two lines of code for both PyTorch and TF2 users.
+* We released a model similar to the English `bert-base-uncased` model (12-layer, 768-hidden, 12-heads, 110M parameters).
+* We chose to follow the same training set-up: 1 million training steps with batches of 256 sequences of length 512 with an initial learning rate 1e-4.
+* We were able to use a single Google Cloud TPU v3-8 provided for free from [TensorFlow Research Cloud (TFRC)](https://www.tensorflow.org/tfrc), while also utilizing [GCP research credits](https://edu.google.com/programs/credits/research). Huge thanks to both Google programs for supporting us!
+
+
+## Requirements
+
+We published `bert-base-greek-uncased-v1` as part of [Hugging Face](https://huggingface.co)'s [Transformers](https://github.com/huggingface/transformers) repository. So, you need to install the transfomers library through pip along with PyTorch or Tensorflow 2.
+
+```
+pip install transfomers
+pip install (torch|tensorflow)
+```
+
+## Pre-process text (Deaccent - Lower)
+
+In order to use `bert-base-greek-uncased-v1`, you have to pre-process texts to lowercase letters and remove all Greek diacritics.
+
+```python
+
+import unicodedata
+
+def strip_accents_and_lowercase(s):
+   return ''.join(c for c in unicodedata.normalize('NFD', s)
+                  if unicodedata.category(c) != 'Mn').lower()
+
+accented_string = "Αυτή είναι η Ελληνική έκδοση του BERT."
+unaccented_string = strip_accents_and_lowercase(accented_string)
+
+print(unaccented_string) # αυτη ειναι η ελληνικη εκδοση του bert.
+
+```
+
+## Load Pretrained Model 
+
+```python
+from transformers import AutoTokenizer, AutoModel
+
+tokenizer = AutoTokenizer.from_pretrained("nlpaueb/bert-base-greek-uncased-v1")
+model = AutoModel.from_pretrained("nlpaueb/bert-base-greek-uncased-v1")
+```

+# bert-base-multilingual-uncased-sentiment
+
+This a bert-base-multilingual-uncased model finetuned for sentiment analysis on product reviews in six languages: English, Dutch, German, French, Spanish and Italian. It predicts the sentiment of the review as a number of stars (between 1 and 5).
+
+This model is intended for direct use as a sentiment analysis model for product reviews in any of the six languages above, or for further finetuning on related sentiment analysis tasks.
+
+## Training data
+
+Here is the number of product reviews we used for finetuning the model: 
+
+| Language | Number of reviews |
+| -------- | ----------------- |
+| English  | 150k           |
+| Dutch    | 80k            |
+| German   | 137k           |
+| French   | 140k           |
+| Italian  | 72k            |
+| Spanish  | 50k            |
+
+## Accuracy
+
+The finetuned model obtained the following accuracy on 5,000 held-out product reviews in each of the languages:
+
+- Accuracy (exact) is the exact match on the number of stars.
+- Accuracy (off-by-1) is the percentage of reviews where the number of stars the model predicts differs by a maximum of 1 from the number given by the human reviewer. 
+
+
+| Language | Accuracy (exact) | Accuracy (off-by-1) |
+| -------- | ---------------------- | ------------------- |
+| English  | 67%                 | 95%
+| Dutch    | 57%                 | 93%

+# German BERT for literary texts
+
+This German BERT is based on `bert-base-german-dbmdz-cased`, and has been adapted to the domain of literary texts by fine-tuning the language modeling task on the [Corpus of German-Language Fiction](https://figshare.com/articles/Corpus_of_German-Language_Fiction_txt_/4524680/1). Afterwards the model was fine-tuned for named entity recognition on the [DROC](https://gitlab2.informatik.uni-wuerzburg.de/kallimachos/DROC-Release) corpus, so you can use it to recognize protagonists in German novels.
+
+
+# Stats
+
+## Language modeling
+
+The [Corpus of German-Language Fiction](https://figshare.com/articles/Corpus_of_German-Language_Fiction_txt_/4524680/1) consists of 3,194 documents with 203,516,988 tokens or 1,520,855 types. The publication year of the texts ranges from the 18th to the 20th century:

+
+
+### Results
+
+After one epoch:
+
+| Model            | Perplexity |
+| ---------------- | ---------- |
+| Vanilla BERT     | 6.82       |
+| Fine-tuned BERT  | 4.98       |
+
+
+## Named entity recognition
+
+The provided model was also fine-tuned for two epochs on 10,799 sentences for training, validated on 547 and tested on 1,845 with three labels: `B-PER`, `I-PER` and `O`.
+
+
+## Results
+
+| Dataset | Precision | Recall | F1   |
+| ------- | --------- | ------ | ---- |
+| Dev     | 96.4      | 87.3   | 91.6 |
+| Test    | 92.8      | 94.9   | 93.8 |
+
+The model has also been evaluated using 10-fold cross validation and compared with a classic Conditional Random Field baseline described in [Jannidis et al.](https://opus.bibliothek.uni-wuerzburg.de/opus4-wuerzburg/frontdoor/deliver/index/docId/14333/file/Jannidis_Figurenerkennung_Roman.pdf) (2015):

+        the `xlm-mlm-en-2048 <https://huggingface.co/xlm-mlm-en-2048>`__ architecture.
+
+        Configuration objects inherit from  :class:`~transformers.PretrainedConfig` and can be used
+        to control the model outputs. Read the documentation from  :class:`~transformers.PretrainedConfig`

+                Path to a directory in which a downloaded pre-trained model
+                configuration should be cached if the standard cache should not be used.
+            force_download: (`optional`) boolean, default False:
+                Force to (re-)download the model weights and configuration files and override the cached versions if they exists.

+                Do not delete incompletely received file. Attempt to resume the download if such a file exists.

+                A dictionary of proxy servers to use by protocol or endpoint, e.g.: {'http': 'foo.bar:3128', 'http://hostname': 'foo.bar:4012'}.
+                The proxies are used on each request.
+            output_loading_info: (`optional`) boolean:
+                Set to ``True`` to also return a dictionnary containing missing keys, unexpected keys and error messages.
+            kwargs: (`optional`) Remaining dictionary of keyword arguments:
+                Can be used to update the configuration object (after it being loaded) and initiate the model.
+                (e.g. ``output_attention=True``). Behave differently depending on whether a `config` is provided or
+                automatically loaded:
+
+                - If a configuration is provided with ``config``, ``**kwargs`` will be directly passed to the
+                  underlying model's ``__init__`` method (we assume all relevant updates to the configuration have
+                  already been done)
+                - If a configuration is not provided, ``kwargs`` will be first passed to the configuration class
+                  initialization function (:func:`~transformers.PretrainedConfig.from_pretrained`). Each key of
+                  ``kwargs`` that corresponds to a configuration attribute will be used to override said attribute
+                  with the supplied ``kwargs`` value. Remaining keys that do not correspond to any configuration
+                  attribute will be passed to the underlying model's ``__init__`` function.
